SS2205 Paʻi Paʻi Paʻa Paʻa ʻelua

E nānā i ka valve, i ʻike ʻia ʻo ka valve hoʻokahi ala, ka valve check, back pressure valve, ua wehe ʻia a pani ʻia kēia ʻano valve e ka ikaika i hana ʻia e ke kahe ʻana o ka mea waena i loko o ka pipeline, a no ka valve aunoa.ʻO ka hana o ka valve check ka mea e pale ai i ka hoʻihoʻi ʻana o ka waena, ka hoʻohuli ʻana o ka pāpaʻi a me kāna kaʻa hoʻokele, a me ka hoʻokuʻu ʻana o ka medium i loko o ka ipu.He ʻano maʻamau maʻamau o ka pahu pahu pahu pālua.Ma ke koho ʻana i nā mea ʻokoʻa, hiki ke hoʻopili ʻia ka wafer check valve i ka wai, ka mahu, ka aila i ka petrochemical, metallurgy, mana uila, ʻoihana māmā, meaʻai a me nā ʻoihana ʻē aʻe., nitric acid, acetic acid, ikaika oxidizing medium a me ka urea a me nā media ʻē aʻe.

ʻO ka pahu pahu pālua pālua, ʻelua-lobed circular disc i hoʻopaʻa ʻia ma ke kino valve me kahi pine pine.ʻElua pūnāwai torsion ma ke kumu pine.Hoʻokomo ʻia ka diski ma ka ʻili hoʻopaʻa o ke kino valve, a kaomi ʻia ka pūnāwai e ke kaomi waena.ʻO ka pāpale butterfly, ke hoʻohuli ʻia ke kahe, e pani i ka valve e ka ikaika o ka puna a me ke kaomi waena.ʻO kēia ʻano ʻano o ka pahu lele lele ka hapa nui o ke ʻano wafer, liʻiliʻi i ka nui, māmā i ke kaumaha, hilinaʻi i ka sila ʻana, a hiki ke hoʻokomo ʻia i nā pipeline ākea a me nā paipu kū pololei.
